Gemini 3.8 text-to-speech says hello

Google has released Gemini 3.8 Flash TTS and Gemini 3.8 Flash-Lite TTS, two new text-to-speech models (AI systems that convert written text into spoken audio) that allow creators and developers to generate highly expressive custom voices with detailed control over performance, tone, and character. These models support over 100 languages, offer 2,000+ pre-made voices, enable voice replication from short audio samples, and allow line-by-line direction of how dialogue is delivered in applications like gaming, podcasts, and interactive media.
